Hi,
I'm a graduate student at the University of
California, Irvine. Firstly, thank you for all the copious
resources. It is a treasure trove of information and a
beacon of light for someone just starting out.
Let's begin with some brief background. In my
research group, we intend to perform pump-probe
spectroscopy with attosecond x-ray probes. The Professor
says that we can use XAFS to study how the electrons move
on these very short timescales. While the system is being
setup and other experiments are being conducted, my
Professor wants me to figure out how to do simulations of
XAFS. This is a bit of a daunting order, since I've never
simulated anything before and only have basic programming
knowledge. The only direction I have is, "Try Google.".
So, today, I've been "trying Google" and found my way
to here. Since, I don't really know what I'm doing, I
thought I try asking and finding out if anyone else does
this sort of thing:
How/where
does one do simulations of dynamic XAFS? Where would I
get started?
(Please
forgive me if this question has been answered somewhere
else or if it seems profoundly dumb or too broad. I'm
really just looking for some more direction. Perhaps, it
could be that nobody does this and, in that case, I need
to figure out how to model this myself. Wow! That
thought seems daunting.)
For example, let's say I want to find out how the
x-ray adsorption of a carbon foil like Graphene would
change on attosecond time scales as it's heated by a
femtosecond laser and electrons move. Is there a program
or code out there that people use to model this sort of
thing?
